This valvo hasn stom i that moves longiudnally of iiself in the stom guiil",y 5 which .is hohl in lixoil rola-tion lo tho cugino to bo stationary. A coiled sinking G surrounds 'cho valve stom and @rouges downwardly thoroon by 'reason of tho ongjaggoilioiit of tho lowor ond of the' spring with a spring scat 'T carried upon tho stein, tho spring thun` serving to close Itho vali/o upon its seat.

Tho upper olnl of lho spring); ong'agos tho llango l() upon l'ho barrol l1. This bai-rol is coaxial with tho \'al\'o jion1 and is rotatable about tho sanno and for tho pui-poso of its rotation ibo upper 0nd of' tho barrol carries a pawl or rollor racoway 12 \\'hif.ih'boa1'.\l upwardly against tho ballsor roller:4 L3 of an anlli-'frirtion braring wiic-h in turn roato upon tho race-way 14v carried by tho engine Strlioturo. Tho spring' not only oxorts tho valve closing Jfunction specified but, in uarh oyolo ol' ils oporation, will causo a partial rotation of tho barrel 1l. Tho spring is enabled to oll'oot such rotation of tho barrel bocauso of (,ho slight twistwhich oci-urs,- bowoon tho omis of iho spring' oaoh timo Atho inning1 is @holnprosswh the. barrol thon boing fro to turn. Altor ho barro-l has boon turned il'J is hohl (by moans to bo not Yforth). `from rovorno rola/ion during tho expansion of tho spring' and until tho spring is again con'iprosaoil to givotho barrol a suromaling turning movomont. Owing;- to the ball bean :ingr struotnro inlorvoning botwoon tho barrel and, Lho engi-no `minimum opposition is 0fforoil in tho rotation ol' the, barrel so that tho barrel may turn whilo tho. spring is boing; compi-eased, tho valvo itsol'lf thon not turning;- owing' to fho braking aolnion iluo to 1the 'i'riotional engagement of its stom with 'tho Yvalve guido and l'ho inertia of tho parts oi tho valve.

A reverse twist occurs botwoon tho owls of the Spring Qn tho expansion lihorool, and as the barrel is hold-from rotation hiring tho expansion of the Spring, tho valvo stom and tho Valve, are turned owing' to tho driving;` connection olI tho lowor end of tho spring;` with the spring seat'y 7 that is nor- .mall y in xod rolation with the yalvo stom. This inovoniont of tho valvo occurs during the closing :inovomcnt thereof amlbcforo it is seated. Un each operation of the valve it is turned to a. slight extent so that constantly new portions ot" the valve and its seat are engaged and the warping, ot' the valve is prevented.l

The means for preventing the rotation of the barrel during the expansion of the spring desir-ably resides in a 'toothed me1nber rotating with the barrel and a seCond but stationary toothed member adapted for tooth engagement with the aforesaid toothed member. 'The toothed member that turns with the barrel comprises faeially toothed wheels 15, 1G, 17 and 18 which are slipped over the guide 5 and therefore surround the valve stein, these wheels being` free to rotate aboutv and with respect to said valve stem and guide. Said wheels Ihave splined connection with the barrel, the splines 151, 1.61, 171 and 181 being provided upon said wheels and entering the spline grooves 111 extending' longitudinally of the barrel and located upon the interior thereof to communicate with the bore ot' the barrel. 'lhe stationary toothed member comprises facially toothed wheels 19, 20 and 2l which are slipped over the guide and therefore alsov surround the valve stem. These wheels are maintained stationary by having: splined connection with the stationary guide 5. To this end the stationary wheels are provided with spline lgrooves which receive the splines` formed on the guide 5 and extending longitudinally thereof. All o'tl the wheels, by reason-otl their splined connections, are adapted to move longitudinally of the valve guide and the barrel, The lower end ot the valve guide carries a spring' abutment 2l: which` is held upon the ruido by a nut which is threaded upon the lower end ot the guide. A coiled spring 26 is seated upon the abutment 2+ and presses against the tootl ed.

wheel 18 to maintain the wheels ot both sets i in as close assembly as possible, the uppermost wheel 15 being pressed against a Flange 5l that is formed upon the guide 5. The various wheels are taelally toothed. The

'bottom face ot the wheel 15 is formed with teeth 152. The top and bottom faces ot the wheel 1G are formed with teeth 162, 1.63. The top and bottom fares of the wheel 17 are formed with teeth 1.72. 173, and the top face of the wheel 18 is termed with teeth 182. The top and bottom `t'aces of the wheel 19 are formed with teeth'ltll, 192. yThe top and bottoni faces of the wheel 2.0 are formed with teeth 201, 202, and the top and bottom faces of the wheel 21 are formed with teeth 211, 212'. All of thesetecth desirably radiate from the common axis of' the wheels. The wheels are adapted to ride over each other owing' to the longitudinal movabilit-y of the wheels which is permitted 'by the spring 2G. The teeth are so directed and shaped that the rotatable teeth '15, 1G, 17 and 18 may recense turn with the barrel 10 during the con1pression ot the` spring (i, reverse'rotation of these particular ttuitlied wheels being prevented the full engagement ot' teeth upon one et these wheels with vthe teeth ot adjacent stationary wheel, the wheels of one set being alternated with the wheels oit the other set.

The teeth of anj,7 plurality of wheels less than the whole number ot eaeh set are in varyingl degrees ot proximity with the engageable teeth of a plurality et' wheels et the other set when the adjacentteeth of any two remaining wheels ot the two sets are in tull enejagement. liig. illustrates the teeth 152 and 191 ot the two wheels 15 and. 19 oit the'tw'o sets in full engagement. The teeth 162, 1)2 et the wheels 1o. lit are nearlyY in lull engagement. rllhc. teeth 163. 20 are t'arther apart than tnelast mentioned teeth. 'l'he teeth 172, 202 are :tai-ther apart.

After such rotation ot' the barrel it is held gagging teeth to attord means against; which the upper end ot' the sprung may react on the expansion of the sprint; to einble the lower cud ot' the spring'. as it twists with re spcct to the upper entt ol the spring; to turn. the valve on the dcscendiugrf movement there of.. tty 'the construction specified a slight turning movement is imparted to the valve 1in cach olf its cyclesl of operation with the advantages that have been specified.
